The dark roast coffee will be available in Timmies locations in Columbus starting Monday and in London as of Monday, Nov. 4.

McKay said the company wants to test the product “to gauge our guests' reactions and gain operations learnings before deciding on next steps,” suggesting a final decision on stocking dark roast hasn’t been made.

Tim Hortons has been under pressure from competitors like McDonald’s who have stepped up their efforts to capture some of the coffee-drinker market. McDonald’s now serves coffee through its McCafe brand, and often offers discounted prices on it.

Tim Hortons has been struggling to make a name for itself in the U.S., despite its overwhelming success north of the border.
